Tensions across the Sahel have escalated following remarks by officials from Mali and Niger at the Dakar International Security Forum, highlighting a widening divide between the Alliance of Sahel States and regional as well as Western partners.

Mali’s foreign minister accused neighboring countries of harboring armed groups operating within its territory, amid deteriorating relations with several states in the region.

The dispute with Mauritania has intensified over allegations of cross-border military activity, claims that Nouakchott has rejected as unfounded.

Regional tensions have also extended further, with Niger previously accusing some West African countries of supporting activities that undermine its stability, contributing to diplomatic strain and disruptions to key routes.

At the forum, Niger’s foreign minister delivered strong criticism of France, accusing it of pursuing policies aimed at maintaining influence through indirect means.

He also criticized Western partners for what he described as inconsistent approaches to counterterrorism, questioning the effectiveness of external support.

Officials from Mali and Niger reiterated claims of external involvement in northern Mali conflicts, allegations that have been denied by those implicated.

At the regional level, divisions with the Economic Community of West African States appear increasingly entrenched, with Mali rejecting any prospect of rejoining the bloc while remaining open to limited cooperation in trade and movement.

The developments reflect a growing split in regional security structures, with competing alliances shaping the Sahel’s geopolitical landscape.

Analysts warn that continued fragmentation could prolong instability, as coordination declines and mistrust deepens across the region.
